VEHICLE-TIRE.

SPECIFICATION forming part of Letters Patent N o. 681,310, dated August 27, 1901. Application filed January 5, 1901. Serial No. 42,151. (No model.)

To all whom it may concern.-

Be it known that I, JOHN GLENN, a citizen of the United States, residing in the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Vehicle-Tires, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to rubber tires for vehicle-wheels, the tire being of a construction particularly adapted for use on the wheels of motorvehicles.

The object of the invention is to produce a tire of such a construction which is so held to the wheel that it will not become loose or separated from the wheel-rim under the strain thereon caused by excessive tractional strain between the wheel and the ground in the propulsion of vehicles that are operated by selfcarried motors.

The invention consists in features of novelty hereinafter fully described, and pointed out in the claim.

Figure I is a perspective View showing a fragment of a whee1-ri1n constructed in ac- 1 cordance with my invention. Fig. II is a perspective view of a fragment of rubber tire constructed in accordance with my invention. Fig. III is a perspective view of afragment of one of the tire-retaining rings. Fig. IV is a crosssectional view of the wheel-rim and tire, showing the tire as it appears in the act of placing it upon the rim. Fig. V is a crosssectional view of the rimvand tire at the location of one of the tire-retaining cross-bars carried by the wheel-rim. Fig. VI is a similar View to Fig. V, .taken through the rim and tire at a location between two of the tire-retaining cross-bars.

1 designates the telly of the wheel-rim,which is encircled by a metal band 2.

3 designates cross-bars positioned at intervals upon the perimeter of the wheel, the bars partaking, preferably, of the shape of dovetail tenons and being secured by any suitable means, such as screws 4, that pass through the metal band 2 and into the felly 1. Each of the cross-bars 3 preferably extends beyond the sides of the wheel-rim, as seen in Figs. I, IV, and V.

6 designates the rubber tire, that may have a tread of any suitable shape.V Projecting outwardly at the base of the tire 6at each side thereof, are ribs 7 of such width that they project beyond the sides of the rim of the wheel, as seen in Fig.l VI. p Each of the ribs 7 is provided with inwardly and downwardly tapering upper faces 8, and at intervals throughout the ribs are notches 9, the purpose of which will hereinafter appear. Extending crosswis'e through the base of the tire are grooves l0, that are adapted to receive the crossabars 3, carried by the wheelrim. The grooves 10 are dovetailed to correspond to the shape of the cross-bars 3, so that said cross-bars will be firmly seated in the grooves when the tire is applied to the rim of the wheel. By the engagement between the tire and wheel-rim, through means of the cross-bars seated in the grooves 10, the tire is retained from slippage on the circumference of the wheel-rim, owing to a iirm hold being thus effected between the parts at frequent intervals throughout the wheels circumference.

11 designates retaining-rings applied to the sides of the wheel-rim and secured thereto by bolts 12, that pass through apertures 1" in the felly l. The retaining-rings l1 are provided on their interior sides with grooves 13, separated at intervals by tenons 14. (See Fig. III.) The grooves 13 are provided with inwardly and downwardly tapering upper faces 15, (see Figs. III, V, and VL) that correspond to the shape of the upper faces 8 of the rubber tire 6, that receive them. The grooves 13' receive the ribs 7 when the retaining-rings ll are placed in position against the sides of the wheel-rim, as seen in Fig. VI, and when the elastic ribs have been pressed into place in said grooves they are firmly held in place by reason of the ribs being wider at their edges than at the junction between them an l the main body of the tire.

It will therefore be seen that the tire is firmlyl held to the wheel-rim, so that any strain upon it cannot cause it to be pulled therefrom. The tenons 14 between the grooves 13 and at the inner sides of the retaining-rings enter the notches 9 in the ribs 7 and add additional security against the slippage of the IOO tire around the circumference of the Wheelrim, thereby acting in conjunction with the cross-hars 3 and serving the same purpose as such cross-bars.

In applying the tire to the rim of the wheel it is first slipped thereonto in the manner illustrated in Fig. IV, `in`which 4action the cross-bars 3 enter the grooves 10 in the rubber tire. After the tire has been applied to the rim the retainining-rin gs 11 are positioned at the sides of the wheel-rim and are pressed against the ribs '7 to cause said ribs to enter the grooves 13. The bolts l2 are then inserted and tightened and the wheel is in condition for use. The overhanging edges of the retaining-rings ll serve to retain the cros`s esimo bars 3 and relieve the strain upon the screws 4, as seen in Fig. V.

I claim as my invention-'- The combination with a Wheel-rim, of a tire having laterally-projecting ribs pro vided at intervals with notches, and independent retaining-rings applied to the sides of the Wheel-rim and having grooves adapted to reV l ceive the ribs of said tire and having tenons adapted to enter the notches in said ribs, substantially as described.
